Also I'm not sure what definition of fungible you are using that doesn't include Bitcoin Cash, but here's another spurious definition for you: A cryptocurrency isn't fungible if most wallets have balances that can't be spent because of fees.
The usual definition of fungible is that one coin (more precisely, one spend output) is as good as another (e.g., the same amount coming from a different UTXO) and they are not distinguishable from each other due to their provenance.
Put more simply, if the coins can be 'tainted' because they were transferred to you from a ransomware hoard then they're not fungible because a merchant could say: "I'm not taking those coins, I don't want to be associated with ransomware. You have to pay me with other coins."
Neither BTC nor BCH has this kind of fungibility, though Monero does.
It isn't as decentralised as Monero. 5 pools control 60% hashrate for BCH, the top 5 XMR pools control 13% (Yuge difference). Also, Monero has a dynamic block size, so it is somewhat future proofed while BCH has another hardfork if it is successful. And fungible means that each unit of the currency is indistinguishable from another unit. BCH and Bitcoin both leave trails, therefore, are not fungible.
This is a really bad catchphrase by the bcash crowd because it sets up bcash as “electronic cash” vs btc “store of value”, when bcash is actually both, as in Satoshi’s vision. Shame bcash is spearheaded by such an untrustworthy team. Their argument is in the right but held back by poor tactics.
and here i thought that scaling distributed systems is very hard problem. it turns out you just bump a number in configuration. quick, patent it and sell to google for billions!
We managed to scale the internet from dial-up to broadband without needing any hardcoded bitrate parameters imposed across the whole network. Bitcoin Cash seems to be doing just fine with its 8 megabyte blocks.
